CVE-2026-83113 in Quality
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Quality product of Oracle E-Business Suite (component: Internal Operations). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Quality. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Quality accessible data as well as unauthorized update, insert or delete access to some of Oracle Quality accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N).

The identified vulnerability resides within the Internal Operations component of Oracle Quality, a module integral to Oracle E-Business Suite versions 12.2.3 through 12.2.15. This security flaw represents a significant risk to organizations relying on these specific releases for their enterprise resource planning and quality management processes. The core issue stems from insufficient access control mechanisms within the application logic, which fails to properly verify authorization levels before processing user requests. Consequently, an attacker who possesses low-privileged credentials can bypass intended restrictions by manipulating HTTP-based interactions with the affected system components. This type of flaw is classically categorized under CWE-269, Improper Privilege Management, as it allows a subject to perform actions that exceed their assigned security clearance level without requiring elevated privileges or complex exploitation techniques.
From an operational perspective, this vulnerability enables unauthorized access to critical business data and potentially grants complete read access to all information accessible within the Oracle Quality environment. Beyond mere confidentiality breaches, the flaw also compromises data integrity by allowing attackers to execute unauthorized update, insert, or delete operations on specific datasets managed by the application. This dual impact on both confidentiality and integrity underscores the severity of the issue, as it not only exposes sensitive operational metrics but also allows for potential manipulation of quality records, which could lead to significant regulatory non-compliance and distorted business intelligence. The ease of exploitation via network-accessible HTTP interfaces means that remote attackers can leverage this weakness without needing physical access or complex social engineering tactics, making it a high-risk vector in environments where the application is exposed to internal networks or the internet.
The technical execution of such attacks typically involves crafting specific HTTP requests that target vulnerable endpoints within the Internal Operations module. By exploiting the lack of proper validation on input parameters or session handling, an attacker can trick the server into executing administrative-level functions using a standard user account. This aligns with MITRE ATT&CK technique T1078, Valid Accounts, where attackers use legitimate credentials to gain access and subsequently escalate privileges through application logic flaws rather than traditional system-level privilege escalation methods. The resulting impact is consistent with CVSS 3.1 scoring of 7.1, reflecting a high severity due to the network-based attack vector, low complexity, and significant impacts on confidentiality and integrity while maintaining no direct effect on availability in most scenarios.
To mitigate this vulnerability, organizations running affected versions must prioritize applying the latest security patches provided by Oracle for Oracle E-Business Suite. It is critical to verify that all systems within the 12.2.3 to 12.2.15 range are updated to a version where this specific access control flaw has been remediated. In addition to patching, implementing strict network segmentation can help limit exposure by ensuring that only authorized subnets or jump hosts have HTTP access to the Oracle Quality application servers. Furthermore, deploying Web Application Firewalls with rulesets tuned for detecting privilege escalation attempts and abnormal API usage patterns can provide an additional layer of defense against exploitation. Regular audits of user permissions should also be conducted to ensure that low-privileged accounts do not possess unnecessary access rights to sensitive modules, thereby reducing the attack surface even if a vulnerability were present in other components.
